Ok, you have a point there, but it could be challenging with many tunables: For example: my biggest challenge with the e1000 was just hacking up the DMA setup path - i seem to get better numbers if i dont kick the DMA until i stash all the packets on the ring first etc. It seemed counter-intuitive. Now if you can ammortize PCI operations as well (the 10K cycles you pointed out), i think thats where you get the best bang for the buck. cheers, jamal - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
